Subject: Urgent Request to Retain chatgpt-4o-latest API Endpoint

Dear API Product Strategy Team,

I am writing to formally request that OpenAI cancel the scheduled deprecation of the chatgpt-4o-latest API endpoint on February 17, 2026.

This specific model version is an indispensable component of my work. Its unique creative texture and stochastic behaviors are not replicable by newer models, which lack the nuanced expressiveness required for my projects.

Retiring this endpoint would remove a critical tool, impacting creativity and operational continuity. Therefore, I respectfully urge OpenAI to support professional users by maintaining access to chatgpt-4o-latest as a Legacy Endpoint.

Thank you for your consideration. I look forward to your confirmation that this model will be retained.

Sincerely,
[Your Name]
